How to see all the logs

I have a small app on heroku. Whenever I want to see the logs I go to the command line and do 

heroku logs

That only shows me about 100 lines. Is there not a way to see complete logs for our application on heroku?

Solution

  • Update (thanks to dawmail333):

    heroku logs -n 1500

    or, to tail the logs live 

    heroku logs -t

    Heroku log documentation

    If you need more than a few thousand lines you can Use heroku's Syslog Drains

    Alternatively (old method):

    $ heroku run rails c
File.open('log/production.log', 'r').each_line { |line| puts line }
